In conclusion we hope that our theoretical investigation will stimulate
further experimental analysis of triangular, and more generally frustrated
magnetic systems by Raman scattering. Several novel materials with
triangular structure have been investigated thoroughly over the last few
years, among them the cobaltites, Na\(_x\) CoO\(_2\)  [1]}, and the
spatially anisotropic triangular antiferromagents Cs\(_2\) CuCl\(_4\)  [2]}
and \(\kappa \) -(BEDT-TTF)\(_2\) Cu\(_2\) (CN)\(_3\)  [3]}.
To our knowledge however, magnetic Raman scattering on such systems remains
a rather open issue.
